my Daughter is like this, starts w/ her butt on the saddle & both sets of toes on the ground. & yes her saddle is too low & she works to hard to keep up. it must have started when she starting learning how to ride. she's 24 now & I can't break her from this. my 25 yr old son son always starts while straddling the top bar, w/ 1 pedal in the up position, puts a foot on it, pushes off with the grounded foot & down on the top pedal with the other foot & off he goes. maybe I spent more time teaching him when he was just starting, but I don't think so. I don't understand because she started tying her shoe laces correctly very young whereas he needed velcro straps on his shoes & then when he got laces, never untied them, just kept them tied & used them like loafers. I still scratch my head if I ever see him tie laces
